Next morning it was "going in" with a vengeance. We did not enter the same trenches where I had been a few days previously, but about a mile farther south. These trenches were our "home" for over three months, so let me try and describe how they were built and looked to us on that day of entry. In this part of the line, near the borders of Belgium, you cannot dig down, the soil is so marshy, so the trenches are what is known as _breastwork_. They are built _up_ about six feet from the level of the ground, a solid wall of sand-bags, ten to twenty feet thick. This will stand the hit of all but the heaviest shells, but is an unmistakable target if the enemy artillery have observation at all. The support and front line trenches were divided every two hundred yards, by communication-trenches, built in the same way, except that the communication-trench had _two_ sides. These communication-trenches were distinguished by such names as "Pinney's Ave.," "V. C. Ave.," which latter was supposed to be built on the spot where Michael O'Leary won the first Victoria Cross of the war. Others were called "Bond Street," "Brompton Ave.," and "Mine Ave." Later on my brigade held the length of trench that included all these, from Mine Ave. to Bond Street, over one thousand yards; but for the battle and the first ten days we only held about three hundred yards, using the three communication-trenches--Pinney's, Brompton, and V. C. I had a good deal of apprehension as the brigade marched in, remembering the reception our reconnoitring party had received. If "Fritz" had spotted a score of us he could not well avoid noticing a thousand, though we were broken into little parties of six, that moved along the gutter in single file. But he must have been asleep this day, for the "change over" was completed with little attention from him in the way of shells. Leading up to "Pinney's Ave.," there was a short length of communication-trench very appropriately called "Impertinence Sap," for it was merely a ditch, three feet deep, floored with "duck boards." I could never get the reason why this trench was built. It only afforded protection for one's legs, which is the part of the body one would rather be hit in if one must be hit at all. The goose-flesh always crept around my head when I walked along this sap, for, strange to say, my head seemed to be the most valuable part of me, and at night the machine-gun bullets used to whistle through the low hedge that ran alongside it and frequently struck sparks from the flints on the old road just a yard or two away. I suppose I used that sap two hundred times, always with misgivings, for I have seen more than a score of men punctured along its length. [Illustration: "Us--Going In".]
